SPECIPICATION formi'g part of Letters Patet No. 299,(356, dated June 3 1884.

Application filed October 17, 1883. (No model.)

To all whom it may concern: y Be it known that we, JOHN' A. LESOURD jand JAMES LOTAN, both of Portland, in the county of Multnonah and State of Oregon, have invented certain new and useful Improvements in Ooal and other Elevators, of which the following is a full, clear, and exact description.

This invention more especially relates to elevators for discharging coal and other substances, but more particularly coal, from the holds of vessels and barges, and has for its object the taking of the material to be discharged from the'ships hold or barge and raising it uninterruptedly and continuously to a suitable height by means of an endless chain provided with buckets to admit of its being run when dumped into any desired receptacle-as, for instance, in the' case of coal into the bins of bunkers of warehouses.

The invention consists in an elevator of this description having combined 'with it one or more hydraulic or other rams for raising it, and 'an engine or engines carried by the ram or rams for working the endless chain of buckets, and in certain constructions and combinations of details and devices for adjusting and holding the endless chain of buckets in position, and for facilitating the general operation of the elevator, substantially as hereinafter described.

An elevator constructedin accordance with this invention will unload and deliver, as required, an entire ship's cargo of coal in avery brief space of time and with great economy.

Reference is to be had to the accompanying drawings, forming part of this specification,

in which similar letters of reference indicate corresponding parts' in all the figures.

Figure 1 represents a side elevation of our improved elevator applied to a barge, shown in transverse section, and in position' for delivering coal taken from the barge at a suitable height into a coaLcarrier for distribution within a series .of bins. front view of the elevator in part; Fig. 3, a broken side View thereof; and Fig. 4, a sectional elevation, upon a larger scale, of the cylinder and valve of one of the engines used to work the endless chaiof buckets.

Ais the endless chain of buckets b, arranged to pass up and down on the outside of a frame, B, having at its upper and lower ends drums Fig. 2 is a broken C C around which the chain travels. The lower drum, C is a frely-moving one, and is rotated by the travel of the chain around it, while the upper drum, C, gives motion to i the chain, said upper drum being mounted on a shaft, c, on which are secured, upon each side of the drum, spur-gears d d, that are rotated and drivenby pinions e e on a crossshaft, f, of two engines, D D. Friction-pulleys or other driving devices may be substituted for the toothed gears d d and e e. The shafts of the drums C C' are set in adjustable boxes g g at the upper and lower ends of the The whole structure so far, including the I frame B, with its drums C C', endless chain A- of buckets, and engines D D, is carried by a strong cross rock -shaft, F, which has its bearings in and is supported upon the tops of two hydraulic rams, G G, on either side of the elevator. This manner of supporting the endless chain of buckets, with its driving appliances and connections, provides for swinging or maneuvering the endless-cha1n carrier -A so as to bring its foot over or in line with the ship s hatchways or the hold of the barge H to be unloaded, and also provides for moving the foot of the endless-chain carrier away therefrom when required.

The engines D D, which serve to give motion to the cross-shaft f by means of cranks k Ic, set at right angles with each other on the end of said shaft, it is proposed to operate by `water -pressure, although steam, which, however, would be objectionable on account of condensation, might be used. They are stopped and started and their speed regulated, as required, by hand-screws l, arranged to actuate link-and-yoke connectionsm, applied IOO to their valves, which it is proposed to make fast on a sten, 72, and arranged to control inlets 0 u and exhaust-ports p p to and from the engine-cylinder. \Vater to drive the engine is admittcd between the heads of the valve of either engine by rubber pipes '7', arranged to connect with the center of the Valve-boxes, and the exhaust or waste water is carried oi'f by similar fiexible conneetions, s, having branches extending to the upper and lower ends of the valve boxes. These rubber or flexible connections adapt themselves to the oscillating motions of the engines. The inlet conneetions r are connected with lower receiving-boxes K by telescoping pipes R, having stnffing-boxes t to prevent leakage of the water under pressure, branches u from ahydraulic main or force-pump serving to conduct the water to said boxes. The ontlet-connections s are also attached to telescoping waste-pipes S for carrying off the exhaust wa ter from the engines and disposing of it as most convenient.

The hydraulic rams G G, which serve to raise and lower the endless chain A of buckets, with its Operating-engines D D and connections, may be either of a single or multiple description, and have any number of stuflingboxes v. For a considerable lift, they should be of a multiple Construction. Said rams are connected below with the receiving-boxcs K, and may have the nsual valves and connections of hydraulic clevators. In cases where the necessary amount of lift is limited, then ordinary or single lydranlic jacks may be used in place of the multiple hydraulie ones.

The operation is as follows: The vessel or barge to be unloaded having been made fast, water from the hydranlic main or force-pump is adniitted to the hydraulic jack or ram or rams G G, to raise bodily the endless chain A of bnckets, with its engines and other connections or applianees, to admit of the foot of said endless-chain carrier being swung on or by the roek-shaft F clear of the ship s rail and over the hatchway or hold of the vessel. The rams G G are then opcrated to lower the endless-chain carrier A down into the hold of the vessel, as shown in Fig. 1, after which the engines D D are started to lift and dscharge, in a continnous or uninterrupted manner, the eoal from the barge or vessel. \Vhen the eoal reaches the top of the elevator, it may be delivered into a chnte, (U, and from thence pass into a carrier at b and be distributed and diseharged within bins c', having screenings-receivers d' below theni or it may be taken from the elevator and dumped in any other way and place or places, as desircd. This uninterrupted discharging operation is continued until the vessel is unloaded, after which the endless chain A of buckets may be raised by the rams G G out of the hold and be swung back to its normal position within a tower, L, until wanted again.

Tackle may be used for swinging or adjusting and holding the endless-chain elevating or discharging device A into position from the shalt F as a center ol' motion, as described; but it is preferred to use a hydraulic manenvering ram or jack, M N, set nearly horizontal, and connected at its outer end with the lower portion of the frame B of the endless chain A of buckets, as such contrivance will afford every facility for pushing the foot of the elevator on board ship and holding it there during the operation of discharging the cargo.

If desired, steam or other mpelling agent may be used in the place of water under pressure for raising the elevator proper or traveling endless chain of buckcts.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is-

l. In eoal and other elevators, the combination of an endless chain of buckets, a laterallyswinging frame carrying the same, and one or more raising and lowering rams or jaeks, on which said swinging frame is nounted, essen tially as and for the purposes herein set forth.

2. In eoal and other elevators, the combination, with one or more raising and lowering rams or jacks, of an endless chain of buckets, a latcrally-swinging frame carrying said chain, and one or more engines, With mechanisn for Operating the chai, all mounted on or carried by the raising and lowering ram or rams, substantially as herein described.

3. The combination of one or more raising and lowering hydranlic jaeks or rams, one or more hydraulie engines carried by said jacks or rams, and a laterally adjustable or swinging endless chain and bucket clevator arranged for operation by said engine or engines, substantially as specified.

4. The combination of the hydraulic jaeks or rams G G, the intermediatcly-arranged endless chain A of buekets, with its drums O C' and frame B, the cross shaft F, and the engines D D, with mechanism for drivin g the upper drum of the chain, essentially as described.

5. The eombination, with the laterally adjustable or swinging frame B and endless chain A of buckets, with its drums C C', of the metallie frames E E', the engines D D, carried by the one of said frames, and the rockshaft F, on or by which the whole are carried, substantially as specified.

(i. The teleseoping inlet and outlet pipes R S and their lcxible connections r s, in combination with the raising and lowering jaeks or rams G G and the engines D D, and laterally adjustable or swingingendlcss chain and bucket elevator carried by said jacks or rams, essentially as described.

7. The maneuvering-ram M N, in combination with the 1aterally-swinging endless chain and bucket elevator, and one or more raising and lower-ing rams, on which said elevator is mounted, suhstantially as specified.
